When you need to read a PDF on a shared PC or from a USB drive, Sumatra PDF Portable can open it without a conventional installation. It also reads several ebook, comic, and document formats, with a compact viewing window centered on the open file.
Can Sumatra PDF Portable run from a USB drive?
Yes. Keep the program in a folder on a flash drive and launch it from there to read documents on another PC. The portable setup avoids installing the reader on each computer, which suits shared machines or environments where installation is restricted.
Because it runs from its own folder, the reader can travel on the same drive as your documents.
Which files can it open?
PDF is the main format, but Sumatra PDF Portable also handles a range of other document and reading files:
- Ebooks: EPUB and MOBI
- Comic book archives: CBZ
- Other document formats: XPS, DjVu, and CHM
How do you open and read a document?
Open a file from the toolbar, and its pages appear in the document window.
It starts quickly and uses little memory, which suits short reading sessions on different PCs.
